Since 2008, photographer Eric Lafforgue ventured to North Korea six times. Thanks to digital memory cards, he was able to save photos that was forbidden to take inside the segregated state

Taking pictures in the DMZ is easy, but if you come too close to the soldiers, they stop you

Yet this is all happening as the world continues to try and cripple the communist regime.

And Kim's own people are being forced to starve, with a shock report revealing 18 million North Koreans aren't getting enough food.

People are also being tortured in his terrifying gulags dotted across the country, where US student Otto Warmbier fell victim to relentless hell after stealing a poster.

The 22-year-old was recently released from the concentration camp back to the US, but died just days later after his family said the regime "brutalised him".

Otto Warmbier: the American student jailed in North Korea for stealing a POSTER

While visiting the hermit state in 2016, Warmbier was jailed for trying to steal a propaganda poster. He was sentenced to 15 years' hard labour in a gulag for "hostile acts against the DPRK." He has been released from North Korea in a coma

Besides cars and yachts, the money flooding into North Korea – and pouring into the state's piggy bank, filled by Pyongyang's illicit dealings – is also being used to build nuclear missiles.

And they are funnelled into Kim's personal pockets, which he uses to buy the loyalty of the party elite and military through cars and luxury watches.

Just last year he showered senior officials with about 100 Swiss-made watches during the Workers Party congress, according to Chinese news site Chosun.

A 2014 UN report states North Korea spent $645.8 million on luxury goods from overseas in 2012, accounting for 16% of that year's total imports of $3.93 billion.

According to CNN: "Experts say these types of purchases are made using Kim's personal piggy bank, filled by Pyongyang's illicit dealings across the globe.

It has been reported the Hermit Kingdom is involved in bank hacking, arms and drug trafficking, currency counterfeiting, and smuggling of endangered species.

According to a 2008 U.S. Congressional Research Service report, CNN stated: "Pyongyang could generate anywhere from $500 million to $1 billion in profits annually from its ill-gotten gains.

"In order to really pressure Kim until he's desperate enough to get to the negotiating table, it is vital to track these illicit funds and cut off that revenue."

Sheena Greitens, a professor at the University of Missouri who is studying North Korea's illicit finance activities, said: "Cutting off the sources of bling can actually have a disproportionately large impact compared to trade flow.

"But cutting off that revenue may prove difficult, like playing a game of international whack-a-mole," CNN added.
